The dogs arrived at Tri-County Humane Society in Boca Raton Wednesday night, where they will be placed up for adoption later this week.

The animals were part of a group of 141 dogs that investigators say they found in Tennessee in the back of a U-Haul moving truck on a cross country journey. Investigators say it appeared the dogs hadn’t been fed or walked in days and were living in filth. The woman who was driving the U-Haul and a female companion are now charged with felony animal cruelty case. If convicted, each faces up to two years in prison.

Two weeks after they were rescued, many of the dogs are doing much better.

“We are finally seeing major improvement in the animals that were so frightened when we first saw them, every single dog goes out twice a day for a walk, they absolutely love it,” said Tracy Reis with the American Humane Association. “We’ve seen just a total change in their attitudes. They’re coming out of their shells. They were very afraid.”
